Abstract

The preparation and characterisation of some new σ-bonded α-unsaturated organic derivatives of tin (SnR¹₄, Sn₂R²₆, SnR³₃Cl, SnMe₂R¹₂, SnMe₃R³, and SnMe₃R¹; R¹ = -CPh = CMe₂, R² = -CMe₂, and R³ = -CPh = CPh₂) is reported. Preliminary crystallographic details are presented for SnR¹₄, establishing the Sn-C bond length and showing the absence of delocalisation in the 1-phenyl-2, 2-dimethyl-ethenyl ligand when bonded to tin. On photolysis, SnMe₃R³ rearranges to 9-phenyl-10-trimethylstannylphenanthrene, apparently without cleavage of the Sn-C bond.
